To all whom it may concern/.1

Be it known that I, EDWARD J. FOGARTY, a citizen of the United States,residing at South Bend, in the county of St. Joseph and State ofIndiana, have invented new and useful Improvements in RailroadCrossovers, of which the following is a specification.

This invention relates to an improved pav ing for railway-crossingswhere a street orroad intersects a railroad-track; and the objectgenerally is to provide a substantial pavement which will be continuousand flush with the top of'the rails to permit pedestrians pnd vehiclesto cross the track on a level surace.

A further object is to provide a construction and arrangement that willrelieve the paving-blocks from jar or vibration incident to the trafficon the track by the railway-cars, and thus prevent displacement of thepavingblocks or their foundation. r

These and other objects will be better understood by reference to thefollowing description and to the accompanying drawings, in which- Figure1 is a perspective view of a paving for a railway street-crossingconstructed in accordance with my invention, with the paving-blocks andtheir foundations shown in transverse section. view of one of thepaving-blocks employed, and Fig. 3 is a perspective view of anotherpaving-block.

Making renewed reference to the drawings, 1 designates the ties, whichare laid in the road-bed as usual, and 2 designates the rails mounted on.the ties, being-secured thereto by any suitable track-fastening.Mounted on the ties on each side of the rail are bed-pieces 3 and 4.These bed-pieces consist of bars of cast-iron that extend parallel withthe rails and have their inner sides sha ed to conform to the web andbase of the rai there being a flan e 5 at the bottom that projectsbeyond the arse-flange of the rail and rests upon the ties,"as shown;These bed-pieces also have upward extensions 6, that flare slightlyoutwardly from the rail and surround the sides of the tread portionthereof, with theirup er surfaces -fiush with the tread of the rail,tffus providing a chair for the rails, and preferably the extension 6 ofthe inner bed-pieces 4 is separated far enough away the rail to providea space or groove for the flange of the wheels of the rolling-stock,whereby the said extensions serve as guard- Fig. 2 is a perspectiveupper surface above the ties,

from the tread of rails. The outer sides of these bed-pieces areconcaved transversely, the concavity extending from the top to ashoulder 7 above the base of the flange 5, the said shoulder forming aseat for the lower inner edge of the paving-blocks-adjacent to thebed-pieces.

' In Fig. 2 one of the paving-blocks 8 is shown as consisting ofsubstantially a rectangular block with one side convexed, as at 9, andthe opposite side provided with a lon gitudinal groove 10. The convexedface 9 is adapted to engage with the concaved face of the bed-piece, asshown in Fig. 1, and the groove 10 is adapted to receive a tongue 11 ofan adjacent block 12, whose opposite face is provided with a similarlongitudinal groove 13 to receive the tongue of another block. I

refer to have the first two or three rows of locks adjacent to thebed-pieces provided with these tongues and grooves; but as this is anexpensive construction the blocks may be of the plain type with straightflat sides, inasmuch as any jar or vibration incident to the traffic onthe rails will not be communicated to the blocks near the center of thetrack or at any great distance from the rails, and therefore the blocksare not liable to be dislodged from their foundation; but in someinstances it may be advisable to employ the tongue-and-grooved blocksthroughout the pavement, while in other instances the tongue-and-groovedblocks may be entirely dispensed with.

The paving-blocks are preferably laid upon a foundation 14 of cement,which is filled in between the-ties and over the same, with its so thatthe foundation for the paving-blocks is entirely =independent of thefoundation for the ties and rails and bed-pieces, and thus the strainsand vibrations upon the rails and bed-pieces are not communicated to thepaving-blocks, but to the ties, as usual.

From the description thus far given it will be seen that each rail issupported and partially inclosed by a chair constituted by thebed-pieces 3and 4, which not only supports the rails, but also, receivesthe strain and vibration incident to the trafiic thereon, and, further,that such strains are communicate to the ties and not to the cementfoundation for the paving-blodks or to the latter. Fur thermore, anylateral vibrations of the bedpieces incident to vehicles crossing thetrack or the rolling-stock upon the rails will not tend to dislodge thepaving-blocks adjacent .to' said bed-pieces because of the contiguouspaving-blocks aid upon said foundation berails, of bed-pieces mounted onthe ties and &

curved faces of the bed-pieces and the blocks 8 adjacent thereto, theelimination of such dislodgment being augmented by the grooveand-tongueconnection of the blocks, though, as before stated, these may be omittedwithout departing from the principle of. m invention. It will also beseen that the b ocks engaging the rails on opposite sides thereof, a bedor foundation laid between and over the ties with its up or surfaceabove the ties, and

tween the bed-pieces.

2. The combination with the ties and rails, of bed-pieces mounted on theties and engagingthe rails on opposite sides thereof, and having theirouter faces concaved, a foundation laid between and over the ties withits upper surface above the ties, paving-blocks 'laid upon saidfoundation between the bedfiieces, the paving-blocks adjacent to theed-pieces having their contiguous faces convexed and fitted into theconcavity of the bed-pieces, substantially as described.

3. The combination with the ties and the rails, of bed-pieces mounted onthe ties and engaging the rails on opposite sides thereof and havingtheir outer faces concaved and also provided witha'basaflange whichrests upon the ties and provides a shoulder at the bottom 'ofthefconcaved face, paving-blocks laid between the bed-pieces, thepavingblocks adjacent to the bed-pieces having convexed faces engagedwith the concaved face of the bed-piece and resting on the shoulv derabove the flange of the bed-piece, substantially as described.

4. The combination with the ties and the I rails mounted thereon, ofbed-pieces mounted on each side of the rail and having baseflangesengaged with the ties, the inner bed pieces having upward extensionsspaced from the tread of the rail to'constituteguardrails, a bed orfoundationlaid between and over the ties with its upper surface abovethe ties and flush with the base-flanges of the bed-pieces, pavingblocksmounted upon said foundations and having tongue-andgrooved connectionswith each other, the

paving-blocks contiguous to the bed-pieces partially resting upon thebase-flanges thereof, substantially as described.

5. The combination with the ties and rails,

of bed-pieces mounted on theties and engaging the rails on oppositesides thereof, pavingblocks interlocking with said bed-pieces, and

a bed or foundation to support said pavingblocks.

In testimony whereof I affix my signature in presence of two subscribingwitnesses.
